In Part-3, the paragraph: "Obviously, this is because there's an implicit conversion from errc to error_condition using a single-argument constructor. Simple. Right?"

Should not say "because there's an implicit conversion from errc to error_code" instead?

This would be great if it were used in boost::asio! Unfortunately, it does not appear to be. From boost/asio/error.hpp:

template<> struct is_error_code_enum<boost::asio::error::basic_errors>
{
static const bool value = true;
};

I can't find a set of error conditions I can use for asio errors; just error codes.
